I saw people yesterday saying this was going to happen. I thought they were exaggerating the level of predictability. BBC headline: Egypt’s Coptic churches hit by deadly blasts on Palm Sunday.

In Alexandria, an explosion outside St Mark’s Coptic church killed 13 people. Pope Tawadros II, head of the Coptic Church, had been attending Mass inside and was unhurt, state media reported.

An earlier blast at St George’s Coptic church in Tanta killed 29 people.

So-called Islamic State (IS) says it is behind the explosions. The group has recently targeted Copts in Egypt.

Four police officers, including one policewoman, were among those killed in Alexandria, the interior ministry said. The suicide bomber blew himself up after they stopped him from entering the church.

It’s like the 16th century, but with better weapons.

The first explosion in Tanta, 94km (58 miles) north of Cairo, took place near the altar.

Security forces later dismantled two explosive devices at the Sidi Abdel Rahim Mosque, also in Tanta, the state-run Al-Ahram news website reports.

The explosions injured at least 71 people in Tanta and 35 others in Alexandria, the health ministry said.

The blasts appear to have been timed for maximum impact, as people gathered to mark Palm Sunday. It is one of the holiest days in the Christian calendar, marking the triumphal entry of Jesus Christ into Jerusalem.

Egyptian security forces had been put on alert in anticipation of attacks.

That concludes this chapter of Today in Religious Violence.
